l M WYMS' Patentedl June 176, 1936 PATENT CFFICE BOTTLEV CLOSURE AND DISPENSER Albert Landrin, Paris, France Application June 29, 1935, Serial No. 29,166

In France July 13, 1934 Y 2 Claims.

bottle closure and dispenser and concerns more particularly bottles in the interior of which a dropping tube is permanently inserted and is only 5 removed during its use or when re-filling.

In an assembly of this kind, the principal problem to be solved is that of absolute fluid tightness, which has necessarily to be ensured between Ythe tube and the stopper of the bottle, so that when the bulb is placed in position, operation shall be normal and ensure the perfect filling of the tube.

In the improvements according to the invention, the tube is mounted in the stopper Vwhich in its turn is screwed on the bottle, the fluid-tightness being ensured by a filling of material, cork or the like, inserted in the interior of a tubular housing carried with the stopper, while being maintained therein by a ange provided on the upper end of the tube. Y

The invention is clearly illustrated in the accompanying drawing, in Which:-

Fig. 1 is an elevational View partly in vertical section showing the bulb applied to the' stopper, the'parts being arranged in position for use,

Fig. 2 is an elevational view of the bulb when separated, and Y Fig. 3 is a view corresponding to Fig. 1 with the bulb removed and the closure cap applied to the stopper.

'Ilhe bottle, of any type, is shown at l and terminates, in the ordinary manner, in a neck 2 having an external screwthread, on which is l screwed a stopper 3 with the interposition of a V plastic joint 4 pierced by a central hole for the passage of the droppingtube 8. 'I'he stopper 3 is provided about the hole with an upright annular flange 5 of small height on the periphery of which Y is soldered or welded a small tubular housing 6 Y 4 0 of a definite height. On the upper part of the housing 6 is provided an external screwthread for theaccommodation of the closure cap 1. In

. the interior of the said small tubular housing6 is engaged the dropping tube 8, the diameter of 45 which is such that itcan pass freely into the Y cylindrical flange 5 integral withY the stopper 3.V

VThe tube 8 is provided with a lateral flange 9 on its upper end. Y Y

The invention relates to improvements in a In the interior of the housing 6 is a cylindrical filling of plastic material or cork I0, which consequently extends in the interior of the said annular flange 5 of the stopper 3. The dropping tubeY 8 consequently passes through the lling I0 which forms a uuid-tight joint and whichis held and pressed against the ange 5 integral with the stopper 3 by means of the flange 9 provided on the upper end of the dropping tube 8. Due to this arrangement, it willr be seen that absolute fluid-tightness is provided by the lling of plastic'material I0 interposed between the Y whole of the stopper 3 and the ange 9 of the tube. g

When it is desired to utilize the dropper, it is merely necessary to unscrew the cap 'I and to engage the rubber bulb I l in its place on the housing 6. When the tube 8 has been filled by def- Y ormation of the bulb l I, it is merely necessary to unscrew the unit formed by the stopper 3 in order to disengage the bottle l Fluid-tightness is therefore ensured by the washer 4 interposed between the neck'of the bottle l and the stopper 3, and through which passes the tube 8, and also between the tube 8 and the housing 6 of the stopper 3 by the tubular filling of plastic mate rial I0 maintained by the ange 9. Y

The constructional form shown is capable of modifications, for example, the stopper 3 may be surmounted solely by a Vtubular part having two diameters, so as to form a housing for the positioning of the filling IIJ.

I claim:

1. A bottle closure and dispenser including a closure cap having a central opening in the top, an upright annular flange of small height formed about theV opening, a tubular housing xed to the periphery of the flange, a dropping tube arranged through the housing and opening, Vand a lling of plastic material arranged in the housing and about the tube forming a joint and ensuring uidtightness.

2. An arrangement as claimed in claim 1,

wherein a flange is provided on the upper end of,
